TinyMCE in ASP.NET UpdatePanel

December 20, 2014 12:03 pm

TinyMCE is a great HTML editor and it is pretty easy to install and configure the editor on a web page. You should just call the init() function while loading the web page at the client’s browser and the target text-area will be transformed into a nice looking HTML editor.

However, we run into some troubles when we tried to use the TinyMCE editor on an ASP.NET page containing server inputs that are handled by the Microsoft’s UpdatePanel control.More

Online Technical Documentation based on WordPress

December 11, 2014 4:32 pm

Recently, we were asked to implement an online technical documentation solution by one of clients. We had to move the existing offline documents (mainly MS Word and PDF files) to an online accessible format that would also allow the users to modify the documents by themselves. We thought about the following options for implementing this:

We did not choose the custom implementation because it was the most time consuming option. We also did not choose the Wiki software because we found it a bit outdated and too restrictive and finally we focused on the CMS solution.More

WIF SSO and Forms Authentication in ASP.NET

December 8, 2014 4:43 pm

One of the projects on which we are working is a long-lived ASP.NET Web Forms system that is customized for a specific client. It is hosted by another company on a server which is external to the client’s environment and it does not have an access to the client’s internal network. The system is built by using the Form Authentication mechanism to authenticate and authorize the users. The list of users and their hashed passwords is stored into the database and the login functionality works in a classic manner – the credentials provided by the user on the login page are validated against the list of users in the database. If the provided credentials are valid then a new Forms Authentication session is established by calling the standard method FormsAuthentication.SetAuthCookie().

Recently, we had to extend that authentication mechanism by adding a single sign-on (SSO) capability which allows the client to integrate the ASP.NET web application with their internal Active Directory (AD) infrastructure. The requirement was to allow some internal employees to access the ASP.NET web application through SSO, but also keep the exiting database login functionality for the rest of the users who are external and they do not have internal AD accounts.

The ASP.NET web application is hosted on an external server and it does not have a direct access to the secured AD infrastructure. After doing some research, we found that in order to connect the external ASP.NET web application to the internal AD environment we can use a middle service called Security Token Service (STS).
